CVE-2023-48126Public exploitNetwork attack vector

Malicious notification injection via exposed access token

Published Jan 26, 2024 · Updated May 29, 2025

Credential exposure in the Luxe Beauty Clinic mini-app on LINE 13.6.1 allows remote authenticated users to send malicious notifications. The members_card endpoint returns the LINE channel access token to client-side code, enabling crafted messages through the Messaging API. Access requires a LINE account and opening the mini-app; the demonstrated consequence is unauthorized notification delivery, not service interruption.
